I'm sure not but you may misunderstand what tar does.  Tar is for storing a 
collection of files into an archive.  It expects to find the list of files on 
the command line in one form or another.  If you don't write to a file first 
then all you have is a stream of data, not a file.

What exactly was the problem?  You may just have a device selection issue.  
What system is this on?
